The History and Impact of British Summer Time: A Global Perspective
31st March 2025

At Foreign Tongues, we understand that global communication plays a crucial role in market research. Whether it is interpreting data or translating cultural nuances, the concept of time itself can shape international interactions. One of the most significant time-related adjustments in the UK is British Summer Time (BST), a topic that remains widely discussed both locally and globally. But why do we have British Summer Time, and how does it affect the international market?
The Origins of British Summer Time
The idea of shifting clocks to make better use of daylight dates back to 1784 when American polymath Benjamin Franklin suggested it as a way to economize on candle usage. However, the first serious proposal in Britain came in 1907 from William Willett. Frustrated by wasted daylight hours in the summer, Willett published a pamphlet titled The Waste of Daylight, advocating for seasonal time adjustments.
In 1916, a year after Willett’s death, Germany became the first country to implement daylight saving time. The UK, along with many other nations engaged in the First World War (1914–1918), followed suit soon after to maximize productivity and conserve energy. Over the decades, daylight saving time spread worldwide, although its benefits have remained a subject of debate.
British Double Summer Time During WWII
During the Second World War (1939–1945), Britain introduced British Double Summer Time (BDST), which advanced clocks two hours ahead of Greenwich Mean Time (GMT) during summer and one hour ahead in winter. This temporary measure aimed to improve wartime efficiency. Post-war, the UK returned to standard British Summer Time, with a brief experiment between 1968 and 1971 when clocks remained permanently one hour ahead.
Should British Summer Time Be Changed?
Over the years, campaigners have pushed for a return to British Double Summer Time or a permanent BST to extend evening daylight hours and reduce energy consumption. However, concerns persist, especially from those in Scotland and northern regions where winter sunrises could be as late as 10 a.m., impacting commuting and school schedules. A proposal in the form of The Daylight Saving Bill 2010–12 was introduced but ultimately failed to pass in the House of Commons.
The European Union and Daylight Saving Time
The British Summer Time Act of 1972 established the tradition of changing clocks in late March and late October. In 2002, the UK synchronized these changes with the European Union (EU). However, in 2019, the European Parliament voted to discontinue daylight saving time within the EU, proposing that member states make their final clock change in 2021. Despite this, the initiative stalled, and EU nations continue to observe seasonal clock adjustments.
A Global Perspective on Daylight Saving Time
Today, around 70 countries implement daylight saving time, predominantly in Europe and North America. Countries near the equator, where daylight duration remains relatively constant year-round, typically do not adopt it. The varying global approaches to time changes illustrate the importance of effective communication and localisation, particularly in industries such as market research, where precise timing and regional awareness are crucial.
Fun Facts About Changing the Clocks
As experts in market research translation, we appreciate the historical quirks of timekeeping. Here are a few intriguing facts about the clocks changing:
- When daylight saving was first introduced in 1916, many worried that delicate clock mechanisms might be damaged by manual adjustments. Newspapers published guidelines to prevent mishaps.
- King Edward VII independently introduced ‘Sandringham Time’ in 1901, setting all clocks on his Norfolk estate 30 minutes ahead to maximize hunting time—a precursor to modern daylight saving!
The Role of Translation in Global Time Adjustments
At Foreign Tongues, we bridge time zone challenges with precise translations tailored for the global market research industry.
